Abstract

AT MAGNETO -OPTICAL RECORDING - AND REPRODUCING EQUIPMENT IS PROVIDED AN ELECTROMAGNET, IN ORDER TO BE ABLE TO REMAGNETIZE THE MAGNETO - OPTICAL LAYER OF A MAGNETO- OPTICAL RECORD IN DEPENDENCE OF BITS TO BE STORED. IN ORDER TO ACHIEVE A FAST AND SAFE REVERSAL OF THE MAGNETIC FIELD, TWO SERIES CIRCUITS CONSISTING OF A FIRST AND A SECOND DIODE (D1 , D 2 ), A SERIES CIRCUITS CONSISTING OF A THIRD AND A FOURTH DIODE (D3, D4) AND A DC - VOLTAGE SOURCE (U) ARE CONNECTED IN PARALLEL TO EACH OTHER. THE COMMON TERMINAL (A) OF THE FIRST AND SECOND DIODE (D1 , D2) ARE CONNECTED VIA A COIL (L) WITH THE COMMON TERMINAL (B) OF THE THIRD AND FOURTH DIODE (D3,D4).THE SECOND DIODE (D2 IS BYPASSED BY A FIRST VARIABLE SWITCH (S1) AND THE FOURTH DIODE (D4) IS BYPASSED BY A SECOND VARIABLE SWITCH (S2). THE TERMINAL (A) OF THE COIL (L) IS CONNECTED VIA A THIRD VARIABLE SWITCH (S3) AND THE OTHER TERMINAL (B) VIA A FOURTH VARIABLE SWITCH (S4) WITH ONE INPUT OF A CURRENT SENSOR (SF), WHOSE OTHER INPUT IS CONNECTED WITH THE COMMON CONNECTING POINT OF THE FIRST AND THIRD DIODE (D1,D3). THE OUTPUT OF THE CURRENT SENSOR (SF) IS CONNECTED WITH THE INPUT OF A CONTROL CIRCUIT (S), WHOSE OUTPUTS (A1,A2,A3,A4) ARE CONNECTED WITH THE CONTROL INPUTS OF THE VARIABLE SWITCHES (S1,S2,S3,S4). THE DIODES (D1, D2, D3, D4) ARE POLARIZED IN BLOCKING DIRECTION WITH THE DC-VOLTAGE SOURCE (U). (FIG.1)
